Microsoft has released four new ads for Windows 8. The video ads are global and are going to be aired in 42 countries joined by printed ads, outdoor posters as well as their online counterparts to help boost user awareness and quick adoption of Microsoft’s latest computer OS.

The advertising agency responsible for the videos is Crispin, Porter and Bogusky and here’s what the agency’s Chief Creative Director Rob Reilly had to say about the ads.

We selected music from up and coming bands. We didn’t want to use overly popular songs because we wanted to bring the viewer on a journey of discovery, both through the storytelling and the music that accompanies these stories. Sometimes, as in “Express Yourself,” by Labrinth we found a new take on a classic old song, much like the reinvention of Windows.

The Microsoft Surface tablet pre-orders has just started in the US and as a result Microsoft has already sold out all its US stock of the base 32GB model (without Touch Cover). If you pre-ordered the 32GB version now you have only wait three weeks before it will delivered to you, while the other two available models are still scheduled to arrive on October 26.

The RT tablet is still available in other countries where Microsoft has started the pre-order yesterday.

If the success of the pre-order is anything to judge by, Microsoft is going to have a pretty successful Surface launch come October 26. However, Microsoft should do its best to bring the device to more countries if it is to mount a serious challenge to the Apple iPad.

Microsoft has now released an ad for Windows 8 that will air on national television, shortly followed by several others. It’s a teaser ad that quickly goes through some of the Windows 8 features, such as the new Modern UI, multi-touch functionality and the ability to run applications side by side. There is a whole lot of other stuff going on as well, with space shuttles launching, laptops exploding and kids breaking piñatas but it’s a Microsoft ad so it was bound to be a bit weird.

Still, this new advertising campaign seems quite good and will definitely make people more curious about Windows 8 and all the new devices that will be launching on October 26.

So we tells you, be sure to check us on October 26, we’ll be there to gives you all what it’s about.
